Oil leakage at the oil filler port is generally due to the injection of too much lubricating oil, which causes the oil level to be extremely high, in a state of overflow, or vibration and turbulence during the operation of the rotary fan to cause oil leakage. There is an oil dipstick in the oil tank of the rotary blower. After the lubricating oil is added, it needs to be between the upper and lower scales of the dipstick. When we inject the lubricating oil, we must add it according to the standard to avoid injecting too much lubricating oil.
